humidification). This means that it could take several hours to achieve a
measurable humidification result. If you put the air washer into operation
in a very dry environment, we recommend that you set the appliance to
continuous operation («Hygrostat» = 5 LEDs) and the speed level to 3 or 4
(«Speed») in order to effectively increase the air humidity level. Here the size
of the room and the ventilation intervals also play a role. (Also see www.

Cleaning
Prior to any maintenance, cleaning and after each use, switch off the appli-
ance and unplug the mains cable (3) from the socket.
Attention: Never submerge the appliance in water (danger of short-circuit).
• For external cleaning, rub with a damp cloth and then dry thoroughly.
• For internal cleaning, remove the water tank (5) and then pull out the wa-
ter tray (2) with the evaporator discs (8) (grab underneath the tray).
• Rinse the water tray (2) and the evaporator discs (8) with clean water once
per week, in order to wash out the particles of dirt removed from the air.
• Clean the water tray (2), evaporator discs (8) and the water tank (5) thor-
oughly every 2 weeks with a soft brush or sponge and warm water. If
there are lime scale deposits in the water tray or water tank, use a des-
caling solution diluted with water (for mixture ratio, see manufacturer’s
instructions). Subsequently rinse the tray and tank with tap water thor-
oughly. The water tray can also be cleaned in the dishwasher (at a maxi-
mum of 60 ° C).
• Descale the evaporator discs (8) approx. every 4 weeks, depending on the
water hardness level. To do so, first empty out any water remaining in the
water tray (2). Then fill the water tray with a descaling solution (mixture
ratio of solution/water according to the manufacturer’s instructions) up
to 2 cm below the edge of the tray (leave the evaporator discs in the tray).
Now push the water tray back into the appliance (the tank does not have
to be inserted). Activate the cleaning mode by simultaneously pressing
the buttons «Speed» (9) and «Dimmer» (12). All white LEDs will now flash
as a sign that the cleaning mode is active. Here the evaporator discs ro-
tate but the fan does not run. Thus no air is blown into the room. After
20 minutes in cleaning mode, the appliance stops and the LEDs go out.
The cleaning process may be run several times depending on the thick-
ness of the limescale deposits. Once the cleaning process is finished,
switch the appliance off using the On/Off switch (4). Empty the water
tray and clean it thoroughly with tap water. The evaporator discs can also
be cleaned in the dishwasher (at a maximum of 60 ° C).
• Make sure that the air inlet and outlet are cleaned regularly to prevent
the build-up of dust. Clean the air outlet (17) with a dry brush or vacuum
cleaner. The air inlet grid (16) is fitted with an air filter which can be re-
moved and cleaned with a damp cloth. Remove the filter by pulling out the
flap at the bottom using the recessed grip.
Silver Cube™
The Silver Cube (15) prevents the growth of germs and bacteria in the hu-
midifier due to the continuous release of silver ions. The use of the Silver
Cube leads to a hygienic room climate. The lifetime of the Silver Cube is
around one year. We therefore recommend that you replace the Silver Cube
